This is an adage in the tactical shooting arena. The goal of tactical shooting is to draw and put effective rounds as fast as possible on the target. There are a couple of elements. one, you want to be faster than the other guy. Yes, but you also want to be accurate.

So in order to train that, you have to imprint the right patterns of movement. So, by slowing down, you gain accuracy. Training this way allows you to imprint good and correct habits, which allow you to gradually increase speed until you can find the sweet spot between speed and accuracy.

So, even in practices where martial effectiveness is even MORE relevant like CQB, Combatives I spend my coaching time trying to get guys to slow the heck down more than I ask them to speed up!

If you can't do it right slow...adding speed is going to make it better? in most cases no. However sometimes speed and audacity count for alot too! usually not....we strive for a better product than one that depends on timing and luck!
